Ukubekwa uphawu okuthuthukile
Lapho uketshezi oluhambayo, igesi, uthuli neminye imidiya esepayipini kucindezelwa, ingcindezi yodebe lokuvala olunamathele ebusweni bomzimba wepayipi nayo iyaqiniswa. Ngosizo lwesakhiwo sedivayisi, akuvinjelwa kuphela ukuvuza kwento esepayipini, kepha futhi nokusebenza kokuphela kwepayipi kuqinisekisiwe.
Ngesikhathi sokuminyanisa, ngokwesimiso se-basiger se-hydrodynamics, uma kwenzeka ubekwa uphawu, kunengcindezi ejwayelekile elingana nengcindezi yangaphakathi kuzo zonke izindawo zokuxhumana nomuntu ophakathi nendawo, ngakho-ke udebe lwangaphansi kwendandatho yokufaka uphawu lucindezelwe, i-lip icindezelwe i-axially, indawo yokuxhumana phakathi kwendebe yokufaka uphawu nepayipi iyanwetshwa, futhi ingcindezi yokuxhumana iyanda, ukuze kuzuzwe umphumela wokuzibopha, njengoba kukhonjisiwe ku-Figure1.
Ngaphansi kwesenzo sengcindezi, indawo yokufaka uphawu kanye nepayipi kuxhumene kakhulu, okungaqinisekisa ngempumelelo ukubekwa uphawu. Kungabonakala kusuka ezimeni zokusebenza zangempela ukuthi indandatho yophawu iyisigxivizo esimile ikakhulukazi, futhi izimo zokusebenza eziqatha ngokwedlulele ikakhulukazi ukudlidliza okuncane nomthelela wokudlidliza. Ngokuya ngezimpawu zohlobo lwe-Y, indandatho yophawu ingathwala uphawu olunamandla olungaphezulu kwama-20MPa.
Igobolondo yingxenye enkulu yengcindezi ethwala isixhumi sepayipi, ethinta ngqo ukuphepha nokuthembeka kokusetshenziswa kwangempela. Kuyadingeka ukwenza ukuhlaziywa okuningiliziwe kwemishini yokwakheka ukuthola ukuthi amandla ephoyinti ngalinye lokucindezela ngaphansi kwengcindezi yokusebenza elinganisiwe ahlangabezana yini nesidingo sokusetshenziswa, thola iphuzu lokuhlushwa kwengcindezi, futhi wenze ukuguqulwa nokuthuthuka okuhambisanayo, ukuze kuqinisekiswe ukuphepha nokwethembeka.
Amandla egobolondo ahlobene namandla we-tensile, ductility, ubukhulu nezinye izinto zezinto ezisetshenzisiwe. Amandla okubopha amabhawodi asetshenzisiwe azodala ukuguquguquka okuthile kwegobolondo. Ngaphezu kwalokho, umlomo wegobolondo nawo uzokhubazeka ngaphansi kwengcindezi. Lezi zinto yizinto ezithinta ukumelana nengcindezi, ukuphepha nokwethembeka kwegobolondo.
Imodeli yesici esilinganiselwe yegobolondo iyasungulwa, njengoba kukhonjisiwe ku-Figure2.
Ukumelana okukhiphayo okuthuthukile.
Imikhawulo emibili yejoyini yamukela isakhiwo se-clasp esihlakaniphile. Ngemuva kokufakwa, i-clasp kuhlobo lwamazinyo indandatho engaguquki iqinisa ubuso bepayipi. Lapho ingcindezi ngaphakathi kwepayipi inyuka noma amandla e-axial ekhuphuka ngenxa yethonya lamandla angaphandle, i-clasp izoqinisa umzimba wepayipi
